Im haveing a motor built by ( RNH Performance) soon. It will be a 331 with my current set up with the addition of either EDDY performer heads or TFS TW heads, and 8lbs of boost. On the old motor I was at 370 rwhp at 5000 rpms and the AFR went rich after 5200. My fuel system will consist of a 255 pump, Aeromotive FPR, 42lb injectors. Im hoping to make around 450 rwhp. I hear verying opinions about what is ok. If I have to goto a new fuel rail set up its going to put a pretty good dent in my budget, plus I will have to buy a new FPR. Any body here making this kind of power or close to it with the stock rails.
